(Guitar Educational). If you're a guitarist who's learned the pentatonic scale up and down the neck but still asks, "During a solo, how do I know what to play and when to play it?", then this book is for you. Its goal is to give you a variety of great blues licks that you can put together bar by bar to create a complete blues solo. Covers: the 12-bar blues progression, cool riffs, complete solos and more. The included audio features "Music Minus Me" tracks that let you play along as the featured soloist. The price of this book includes a unique code that provides access to audio tracks online, for download or streaming. The tracks include PLAYBACK+, a multi-functional audio player that allows you to slow down audio without changing pitch, set loop points, change keys, and pan left or right available exclusively from Hal Leonard.
